ROTARY' ENGINE.

SPECIFICATION forming part of Letters Patent No. 297,589, dated April 29, 1884.

Application filed January 9, 18S-l. (No model.) Patented in Germany May 7, 1882, No. 22,356.

T0 all whom it may concern:

Be it knownthat I, CARL ENKE, of the city of Nuremberg, in the Kingdom of Bavaria, German Empire, have invented `an Improvement in Rotary Engines; and I do hereby declare that the following specication is a full description of the same, reference being had to the accompanying drawings, forming part of this specification.

Similar letters of reference indicate corresponding parts inthe several figures.

Figure 1 is an elevation of the machine, partly in section. Fig. 2 is a plan. Fig. 3 is a vertical section of the cylinder. Fig. 4. is an inside view of the cylinder; Fig. 5, an outside view. Fig. 6 is a vertical section of the two piston-wheels, of which Fig. 13 shows one in a view. Figs. 7, 8, 9 show one piston-wheel in;

section and elevation, and a plan of two such wheels at the point of their narrowest gearing. Figs. 10, 11, 12 represent a piston-wheel in a plan view, and two such wheels at the point of their narrowest and widest position.

To facilitate the understanding ofthe invention, imagine two bevel-gears-the shafts or axis of which form a very obtuse anglewith very coarse and long teeth inclosed in a casing in such manner that every empty space not necessary for the rotary motion of the two gears is lled up or avoided, and steam admitted at one side of the contact-point of the two pitchlines, leaves the casing at the other side of this point. Then the steam will have pressed upon the same sides of the teeth of the gears and forced the latter to rotate. v This idea explains the character of the machine towhich my invention is applied.

The invention consists in the novel combination of parts hereinafter more clearly pointed out and claimed.

Upon the shaft e e are mounted two bevelgears, c c', the teeth of which, t t, Figs. 6 and 13, are gearing at the lower side of these iigures As gear-teeth in their propel and correct form would not be practicable for the object they have to perform in the present case, each of the teeth t t is radially extended,so as to form paddles or pistons b b', which, not having the exactly correct form of teeth, nevertheless near each other closely enough at the the entrance of steam (or water) at the lower l point of gearing, where the teeth come in close contact, as shown in Fig. 11,while in Fig. 12 is represented the position of the pistons b b in their top position. The shafts e e form with each other an obtuse angle and the small space between the gears c a and the teeth and pistons tfb t b is as much as possible lled up by a casting or filler, d, suitably shaped, with a tail-piece, d', Fig. 6. These shafts turn in suitable bearings, and the gears, with their pistons, are inclosed into a corresponding casing, which, made in two parts, receives and secures the tail-piece cl.

Instead o'f attaching the pistons b b directly to the teeth t t and in one casting, they may be made separate from them.

Figs. 1, 7, 8, and 9 show the pistons b b attached to the rim of the disks g g,mounted to the shafts e e, which carry also the bevel-gears a a. The filler d is fitted steam-tight to recesses of the disks 'g g incasing the gears aa', and fastened by its tail-piece d between the crooked flanges of the two halves c c of the engine case or cylinder. (See also Fig. 4.) The cylinder cc ris provided at its centers with bearings and stuffing-boxes for the shafts e e',

and mounted to' foundation-plate, which sup- I ports also two further pillow-blocks for the shafts e e. `The cylinder c c is provided also with two short iianged pipes, fj", for the admission and the exhaust of the steam, or for the suction and the forcing of fluids if the design is used as a pump, in which case power is applied at one of the shafts e e', as shown in Figs. 1, 2. The cylinder c c may be constructed in another way, as shown in Figs. 14, 15. The conical parts are made without crooked dan ges, but form two uniform heads, c c', while the filler d is cast in one piece with the upper part of the cylindrically-shaped case or ring d d', the lower part of which is screwed to the upper one. To the recessed anges of this ring the .two heads c c are screwed or otherwise jointed. In these figures is shown also that IOO the bevelgearing a a may be dispensed with c', beveledgear Wheels a a', mounted upon and replaced by the well-known universal shaftsee,thesaid gear-wheels beingconnected joint.
